Burundi 5-FRANCS (KM26)
Buff-spotted flufftail

In 2014, Burundi issued a commemorative set of coins featuring birds. The combined mintage of 1.8 million indicates they are intended for circulation.

The Buff-spotted flufftail (aka Sarothrura elegans) is found in Burundi and other countries in Sub-Saharan Africa. Its tail doesn't look very fluffy to me, but the bird is covered in spots. Buff spots.
